Kankurō was shown to be the type to avoid needless fighting. In the short time between this and the Sasuke Retrivial Arc, Kankurō and Temari no longer expressed fear of being killed by Gaara when sent on missions with him. After Gaara's defeat in the hands of Naruto, Kankurō's relationship with Gaara improved drastically over a very short period of time. This was most evident when he was seen with Gaara, who Kankurō was forced to put up with due to the fear his younger brother imposed on him. This carried over to many of his interactions with other characters, as he was noticeably irritated when in the presence of someone younger than him.
In Part I, one noticeable personality trait he displayed was an apparent dislike for children, first seen when he attempted to beat up Konohamaru for running into him. In the anime, Kankurō mentions having once pleaded with Chiyo to train him, though she turned him down because she no longer cared about aiding the future of the village. Later, he confronted Gaara and asked whether or not he felt remorse for killing his fellow villagers, but was silenced when he threatened to kill him. As his father arrived, Kankurō noted his younger brother was a "monster". In the anime, when Shukaku rampaged in Sunagakure, a young Kankurō instructed the villagers to escape. While it was customary for close relations to a Kage to be a jinchūriki, neither he nor his sister Temari were compatible with the One-Tail. Kankurō was born the second child to Karura and the Fourth Kazekage: Rasa. 10.1.2 Naruto Shippūden the Movie: The Will of Fire.10.1.1 Naruto the Movie: Legend of the Stone of Gelel.9.3 Shikamaru Shinden: A Cloud Dancing in Forlorn Falling Petals.
